Рукопись поступила в редакцию: 28.03.2021. Принята к публикации: 11.05.2021.Received: 28.03.2021. Accepted: 11.05.2021.С тех пор, как Европейский союз стал играть растущую роль в отношениях между государствами-членами и средиземноморскими странами, не входящими в ЕС, политики в Брюсселе стали уделять большое внимание разработке и реализации действий и программ, направленных на поощрение мира, стабильности и развития в регионе. Эффект от такого участия оказался не столь значительным, как ожидалось, но, тем не менее, ощутимым. Напряжение почти всегда витало над водами Средиземного моря, потому что кризисы и жестокие конфликты следовали один за другим, но никогда не разрушали все отношения. Настоящая статья основана на этой особенности Средиземноморья и предлагает взглянуть на этот регион под другим углом зрения. Вопреки преобладающему мнению о Средиземноморье как о зоне, не затронутой или почти не затронутой основными мировыми событиями, в работе анализируется влияние международных институтов и действий, влияющих на Средиземноморский регион. Автор также привлекает внимание читателей к активной, а в некоторых случаях — к пассивной позиции правительств региона в мировых институтах и международной политике. Соответственно, первый раздел предлагает вниманию читателей концепции, пригодные для анализа мира как политического пространства, в котором были созданы институты для проведения политики, реагирующей на проблемы мирового масштаба. Во втором разделе излагаются основные международные подходы к безопасности и экономической политике, которые были разработаны для реагирования на мировые проблемы и, следовательно, для наведения порядка в мире, включая Средиземноморский регион. В третьем разделе основное внимание уделяется прогнозированию мировой и средиземноморской политики ближайших лет с учетом противостояния трех великих держав — США, Китая и России. Препятствия для сохранения в неизменном виде западной коалиции не могут помешать возобновлению гегемонии США, если беспорядок окажется неприемлемым для большого числа стран. Китайская модель экономической открытости и нейтральности компаний-инвесторов может работать не во всех странах Средиземноморья. Нарушая спокойствие и изменяя правила игры в сложных условиях безопасности, таких как Средиземноморье, поддерживая авторитарные режимы, Россия стремится создать ситуацию, в которой Соединенные Штаты Америки и европейские страны не могли бы принимать никаких решений без ее участия. Соответственно, выводы статьи призывают к накоплению знаний о реконфигурации мировых коалиций и изменении международного положения. Особенно тщательно следует исследовать политику ревизионизма трех государств, соревнующихся за мировое лидерство. Первостепенное значение имеют исследования влияния такого глобального процесса на более обширный район Средиземноморья и на участие средиземноморских стран в этом процессе.Since the European Union began to play a growing role in the relationships between the Member States and the Non-EU Mediterranean countries, the policymakers in Brussels have devoted a great deal of attention to devise and implement actions and programmes aimed at promoting peace, stability and growth to the area. The effects of such involvement have been not as signifi cant as expected but not even insignifi cant. Tension has almost always floated over the Mediterranean waters because crises and violent conflicts have followed one another though never breaking all relations down. The present paper takes a cue from this feature of the Mediterranean area and proposes to watch the territory from a different angle of view. Contrary to the prevailing view of the Mediterranean as an area unaffected or scarcely affected by the dominant world policies, the paper analyses the impact of the world policy-making institutions and policies on the Mediterranean area. It also draws the readers’ attention towards the participation and, in significant cases, the non-participation of the governments of the area in the world institutions and policies. Accordingly, the first section highlights the concepts useful to analyze the world as the political space in which policymaking institutions have been established for building policies that respond to world-scale problems. The second section outlines the signifi cant security and economic world policies that have been established for responding to world problems and, consequently, for bringing order to the world, the Mediterranean area included. In the third section, the focus is on forecasting the world and Mediterranean politics of the coming years by drawing the readers’ attention to the confrontation of three big powers, the USA, China and Russia. The difficulty to keep unaltered the Western coalition could not impede the renewal of the US hegemony should disorder be unsustainable to loads of countries. The Chinese model of economic openness and the non-interference of the investing companies may not work in all the Mediterranean countries. By acting as a troublemaker and game-changer in security complex settings like the Mediterranean area by bolstering authoritarian regimes, Russia mostly wants to create a situation in which the United States and the European countries find it impossible to make any decisions without its participation. Accordingly, the paper’s conclusions call for building knowledge about the reconfi guration of the world coalitions and the change of the existing order and institutions. Especially the revisionism of the three states competing for world leadership requires careful investigation. Research on the influence of such a global process on the wider Mediterranean area and the involvement of the Mediterranean countries in such a process is of paramount importance

Evoluzione della sostanza organica in suoli rappresentativi dell'altopiano della Sila

Abstract: Organic-matter evolution of soils from Sila uplands (Calabria, Italy). Soil organic matter (SOM) has long been known for its central role in chemical, biochemical and physiological soil processes. Efforts in optimizing crop production, minimizing environmental pollution, and enhancing soil quality all require a better understanding of the nature and evolution of soil organic matter for its proper management. Four sites (S1 ' S4), developed on an area of about 9000 ha, in the Sila Mountains, were evaluated to study the turnover of the soil organic matter. The SOM of four sites studied undergoes to a fast mineralization process in the sites S1, S3 and S4, a pastureland, a grass-pastureland, and a cropland, respectively. An opposite trend is observed in the S2 site, under mixed forest of coniferous and broadleaf, where prevailed the humification process

LOFT - a Large Observatory For x-ray Timing

The high time resolution observations of the X-ray sky hold the key to a number of diagnostics of fundamental physics, some of which are unaccessible to other types of investigations, such as those based on imaging and spectroscopy. Revealing strong gravitational field effects, measuring the mass and spin of black holes and the equation of state of ultradense matter are among the goals of such observations. At present prospects for future, non-focused X-ray timing experiments following the exciting age of RXTE/PCA are uncertain. Technological limitations are unavoidably faced in the conception and development of experiments with effective area of several square meters, as needed in order to meet the scientific requirements. We are developing large-area monolithic Silicon Drift Detectors offering high time and energy resolution at room temperature, which require modest resources and operation complexity (e.g., read-out) per unit area. Based on the properties of the detector and read-out electronics that we measured in the lab, we developed a realistic concept for a very large effective area mission devoted to X-ray timing in the 2-30 keV energy range. We show that effective areas in the range of 10-15 square meters are within reach, by using a conventional spacecraft platform and launcher of the small-medium class.Comment: 13 pages, 8 figures, 1 table, Proceedings of SPIE Vol. 7732, Paper No. 7732-66, 201

Evaluation of clinical, laboratory and morphologic prognostic factors in colon cancer

<p>Abstract</p> <p>Background</p> <p>The long-term prognosis of patients with colon cancer is dependent on many factors. To investigate the influence of a series of clinical, laboratory and morphological variables on prognosis of colon carcinoma we conducted a retrospective analysis of our data.</p> <p>Methods</p> <p>Ninety-two patients with colon cancer, who underwent surgical resection between January 1999 and December 2001, were analyzed. On survival analysis, demographics, clinical, laboratory and pathomorphological parameters were tested for their potential prognostic value. Furthermore, univariate and multivariate analysis of the above mentioned data were performed considering the depth of tumour invasion into the bowel wall as independent variable.</p> <p>Results</p> <p>On survival analysis we found that depth of tumour invasion (P < 0.001; F-ratio 2.11), type of operation (P < 0.001; F-ratio 3.51) and CT scanning (P < 0.001; F-ratio 5.21) were predictors of survival. Considering the degree of mural invasion as independent variable, on univariate analysis, we observed that mucorrhea, anismus, hematocrit, WBC count, fibrinogen value and CT scanning were significantly related to the degree of mural invasion of the cancer. On the multivariate analysis, fibrinogen value was the most statistically significant variable (P < 0.001) with the highest F-ratio (F-ratio 5.86). Finally, in the present study, the tumour site was significantly related neither to the survival nor to the mural invasion of the tumour.</p> <p>Conclusion</p> <p>The various clinical, laboratory and patho-morphological parameters showed different prognostic value for colon carcinoma. In the future, preoperative prognostic markers will probably gain relevance in order to make a proper choice between surgery, chemotherapy and radiotherapy. Nevertheless, current data do not provide sufficient evidence for preoperative stratification of high and low risk patients. Further assessments in prospective large studies are warranted.</p

The Cherenkov Telescope Array: layout, design and performance

The Cherenkov Telescope Array (CTA) will be the next generation very-high-energy gamma-ray observatory. CTA is expected to provide substantial improvement in accuracy and sensitivity with respect to existing instruments thanks to a tenfold increase in the number of telescopes and their state-of-the-art design. Detailed Monte Carlo simulations are used to further optimise the number of telescopes and the array layout, and to estimate the observatory performance using updated models of the selected telescope designs. These studies are presented in this contribution for the two CTA stations located on the island of La Palma (Spain) and near Paranal (Chile) and for different operation and observation conditions

Performance of the Cherenkov Telescope Array in the presence of clouds

The Cherenkov Telescope Array (CTA) is the future ground-based observatory for gamma-ray astronomy at very high energies. The atmosphere is an integral part of every Cherenkov telescope. Different atmospheric conditions, such as clouds, can reduce the fraction of Cherenkov photons produced in air showers that reach ground-based telescopes, which may affect the performance. Decreased sensitivity of the telescopes may lead to misconstructed energies and spectra. This study presents the impact of various atmospheric conditions on CTA performance. The atmospheric transmission in a cloudy atmosphere in the wavelength range from 203 nm to 1000 nm was simulated for different cloud bases and different optical depths using the MODerate resolution atmospheric TRANsmission (MODTRAN) code. MODTRAN output files were used as inputs for generic Monte Carlo simulations. The analysis was performed using the MAGIC Analysis and Reconstruction Software (MARS) adapted for CTA. As expected, the effects of clouds are most evident at low energies, near the energy threshold. Even in the presence of dense clouds, high-energy gamma rays may still trigger the telescopes if the first interaction occurs lower in the atmosphere, below the cloud base. A method to analyze very high-energy data obtained in the presence of clouds is presented. The systematic uncertainties of the method are evaluated. These studies help to gain more precise knowledge about the CTA response to cloudy conditions and give insights on how to proceed with data obtained in such conditions. This may prove crucial for alert-based observations and time-critical studies of transient phenomena

Sensitivity of the Cherenkov Telescope Array to emission from the gamma-ray counterparts of neutrino events

We investigate the possibility of detection of the VHE gamma-ray counterparts to the neutrino astrophysical sources within the Neutrino Target of Opportunity (NToO) program of CTA using the populations simulated by the FIRESONG software to resemble the diffuse astrophysical neutrino flux measured by IceCube. We derive the detection probability for different zenith angles and geomagnetic field configurations. The difference in detectability of sources between CTA-North and CTA-South for the average geomagnetic field is not substantial. We investigate the effect of a higher night-sky background and the preliminary CTA Alpha layout on the detection probability
